CHANCE OF FLARES: NOAA forecasters estimate a 40% chance of M-class solar flares and a 5% chance of X-flares today. The most likely sources would be sunspots AR1610 and AR1614, which have unstable 'beta-gamma' magnetic fields. Eruptions from AR1614 would likely be Earth-directed.

RED AURORAS: Auroras are usually green, and sometimes purple, but seldom do sky watchers see much red. The geomagnetic storm of Nov. 13/14 was different. It produced auroras with a distinctly rosy hue. David E. Cartier, Sr. photographed the phenomenon near Marsh Lake, about 40 km east of Whitehorse in Canada's Yukon Territory:

"I was amazed by the deep scarlet color, which was immediately recognizable to the unaided eye", says Cartier. Similar splashes of candy-cane red were spotted over Wisconsin and Michigan. The apparition might be related to rare all-red auroras sometimes seen during intense geomagnetic storms. They occur some 300 to 500 km above Earth's surface and are not yet fully understood. Some researchers believe the red lights are linked to a large influx of low-energy electrons. When such electrons recombine with oxygen ions in the upper atmosphere, red photons are emitted. At present, space weather forecasters cannot predict when this will occur. Could more reds be in the offing? NOAA estimates a 30% to 35% chance of polar geomagnetic storms on Nov. 16th and 17th.
